Signing day is coming fast. Next Wednesday, the next round of players will sign up for their respective programs and start what could be storied careers.

Here's what each team across the Big 12 needs. You'll find Texas A&M and Mizzou on the SEC blog and West Virginia on the Big East Blog.

BAYLOR

Quarterback: This one's pretty simple. Robert Griffin III is taking his talents to the NFL early. Nick Florence is waiting to take over, and the Bears have Bryce Petty behind him, but more reinforcements at quarterback are needed. Dual-threat quarterbacks, ideally.

Defensive tackle: Baylor already was one of the nation's worst teams (102nd nationally) at stopping the run. Now it'll need to replace both its interior linemen, Nicolas Jean-Baptiste and Tracy Robertson.

Offensive linemen: Baylor's offensive line, meanwhile, has been solid. It loses junior college transfer and two-year starter Robert T. Griffin, as well as All-Big 12 center Philip Blake. John Jones, a reserve guard, also has exhausted his eligibility.

IOWA STATE

Receiver: This has been a weak spot for the team for several years, and its top overall talent,Darius Reynolds, is gone. Darius Darks is, too. Aaron Horne and Josh Lenz will be the team's best weapons in 2012, but the pair of shifty slot guys will be seniors. This position needs reinforcements.

Defensive back: The DBs have been a quiet strength for ISU, especially in 2011. Cornerback Leonard Johnson and safety Ter'Ran Benton both have exhausted their eligibility, though, and defensive backs coach Bobby Elliott left for Notre Dame. You'll see plenty of new faces in the Cyclones' secondary next year.

Defensive line: Experienced startersStephen Ruempolhamer and Jacob Lattimer are both gone, and Iowa State has struggled to stop the run consistently the past few seasons.

KANSAS

Quarterback: Kansas landed high-profile transfers Dayne Crist (Notre Dame) and Jake Heaps (BYU), but this is still a huge position of need. Last year's starter, Jordan Webb, left the team. Quinn Mecham is out of eligibility. Heaps is sitting out his NCAA-mandated year after transferring. Crist is the starter, but he badly needs a backup, especially if Brock Berglund's transfer appeal allows him to leave.

Wide receiver: Kansas lacks a big threat at this position. It needs a talent upgrade in a big way. Oklahoma transfer Justin McCay is joining the team, but he's no guarantee to a) be granted immediate eligibility or b) become an impact player.

Defensive tackle: Kansas is thin here, too. Richard Johnson, Patrick Dorsey and Michael Martinovich are gone, and Kansas couldn't stop much of anything on defense. Some push up front could help make everything look better. A late addition to the 2012 class from a junior college seems like a no-brainer. The Jayhawks need physically mature players to contribute immediately.

KANSAS STATE

Offensive line: K-State's offensive line was much better in 2011 and could be again in 2012. It needs help replacing All-Big 12 lineman Clyde Aufner, though. Starter Colten Freeze is also gone.

Defensive line: Kansas State is bringing back about as many starters as anyone in the Big 12, but the biggest losses are along the defensive line. Kick-blocking specialist (five in 2011) Ralph Guidry is gone, along with tackle Ray Kibble. Juco transfer Jordan Voelker exploded onto the scene this year, but he's gone, too.

Defensive backs: Cornerback David Garrett leaves a huge hole behind. Tysyn Hartman may not be as talented as teammate Ty Zimmerman, but his experience leaves a big hole. Zimmerman will have to mentor a younger safety in the near future.

OKLAHOMA

Receiver: The Sooners are thin here in a big way. That was obvious late in the season when Ryan Broyles' storied college career ended a few weeks early with a knee injury. The team also lost Justin McCay (transfer) to Kansas. Jaz Reynolds and Kenny Stills are the likely top two targets, but they need help.

Tight end: This position inspired a bit of panic at the end of the season. Seniors James Hanna and Trent Ratterree are gone. Austin Haywood wasn't allowed back on the team, and two more tight ends left the team for various reasons. That left the Sooners suddenly without a scholarship player at the position returning in 2012.

Offensive line: Starting tackle Donald Stephenson must be replaced, as will guard Stephen Good, who moved in and out of the starting lineup throughout his career. The Sooners bring back a lot of talent and aren't dying for depth there, but those two will leave holes. Three more offensive line starters will be seniors in 2012.

OKLAHOMA STATE

Offensive line: The Cowboys need a whole lot of help here to fill in behind young players stepping into the starting lineup. Starters Levy Adcock, Nick Martinez and Grant Garner are gone. Backup center Casey LaBrue is gone, too. Those are two All-Big 12 linemen who leave big shoes to be filled.

Receiver:Justin Blackmon surprised no one by leaving a year early, and Josh Cooper leaves with perhaps the most underrated career of any receiver in school history. In OSU's offense, there's always room for depth here. Nine receivers had at least 19 catches in 2011. Blackmon and Cooper combined for 192, though.

Defensive ends: The pass rush was solid for Oklahoma State this year, but both starters, Jamie Blatnick and Richetti Jones, are gone. Replacing both is a necessity.

TEXAS

Receiver: Texas lacks a true game-changer at the position, though Jaxon Shipley and Mike Davis may develop into that role in 2012. Former blue-chip recruit Darius White left for Missouri, too.

Quarterback: David Ash and Case McCoy didn't show a ton of potential at quarterback this year, though Ash may grow with an offseason to prepare as starter. Garrett Gilbert got a big chunk of the work in the spring, summer 7-on-7 and fall preseason camp. Even if Ash does grow, the Longhorns need reinforcements at the position.

Defensive linemen: TCU isn't losing a lot at this spot, but Ross Forrest and D.J. Yendrey will be seniors in 2012. The Horned Frogs would be well-served to prepare, and offer some depth next year.

Specialists: TCU will have to break in a pair of new starters on special teams next season. Kicker Ross Evans and punter Anson Kelton have exhausted their eligibility.

TEXAS TECH

Receiver: The Red Raiders' offense requires a lot of depth here. Tramain Swindall is the only loss at the position, but three more (Alex Torres, Cornelius Douglas, Darrin Moore) will be seniors. Douglas moved to cornerback this year after the team was racked with injury, but we'll see whether he moves back this offseason.
